Well observed - I have added the "extension specification" situation
to the no-change CP. It makes no difference, however, since it still
means that no change is required.

Well, yeah, that was even too new to slip through. :-) I'll also
mention this in the no-change proposal, even though I am no sure
exactly how it can be used yet - e.g. can it be used inside a <video>
element?
Thanks for noting these.
